I would not use any other A/C insulating panels. These panels are thick, wide and fit perfectly with small window units. They are air tight to keep you from loosing air to the outside. They are also an excellent sound barrier.
These do not compare to the side panels you will get with your a/c unit. They do not have the same measurements i.e. not wide enough. The adhesive panels that you get with the product also do not stick to the unit or window hardly at all. I kept the panels on the unit and put these on the outside as extra insulation. I will tape over them for added insulation and bug protection.
These panels are not meant for average size window units. They are way to wide and long, since they come with hard frame you can not cut them to fit.
The concept is great but doesn't work for older units
